You have a valid point but you are using misleading data: Don't compare a RCE + SBX vs a RCE w/o SBX. Firefox RCE + SBX is 80k, edge is 100k, safari is also 80k.

Another thing to take in consideration is the number of people that the exploit could be used against. For example, following this: http://gs.statcounter.com/browser-market-share/desktop/world..., Chrome would have almost 68% of the browsing share whereas Firefox is only close to 10% and all the others even less. It'd be surprising this isn't taken account by Zerodium in their price calculations!

You're correct -- I was referring to the table that was easiest to quickly reference which is the changelog, not ALL current prices. The periodic table is more accurate. I'll update my post.
